As regard numbering, I do recall that CSK 200 was actually the first CSK off the production line but was numbered 200 and was owned by Charles Spencer King.
Land Rover International did an article many years ago noting that number 200 was owned by a country-pub landlord in the Midlands, thus it should still be in existance I would think.
